This video is about the physics of geosynchronous and geostationary orbits, why they exist, when they don't, when they're useful for communication/satellite TV, etc.

You might think of plate tectonics as destructive since it's the ultimate force behind earthquakes, tsunamis, and volcanic eruptions. But the slow movement of our planet's surface does a lot more than shake things up now and then. Some...

Today Emily Graslie of The Brain Scoop gives us the news about a couple of near- misses for our planet and an update on where astronomers think habitable life might be found in other star systems.

How often do we miss asteroids like 2017 OO1, and what are astronomers doing to limit their impact? Meanwhile, distant icy worlds might not look as promising in our search for extraterrestrial life as scientists once thought.

Earth is unique in that it's the only planet we know of that can support life. But could there be another planet like ours somewhere far away?

Now that scientists have discovered evidence of thousands of other planets, the next question is, obviously, how can we colonize them? Keep these considerations in mind to become a colonial power of galactic proportion.

Why Earth 2.0 may not be such a feasible place for people to live.

NASA's Kepler space telescope has discovered a planet in a habitable zone around a star with similar conditions to our own Sun. Kepler 22b's year is 290 days long and scientsts estimate the surface temperature is around 72 degrees,...

The more we see other planets, the more the question comes into focus: Maybe we're the weird one? Decades of observing Earth from space has informed our search for signs of habitability and life on exoplanets and even planets...

In this video we will begin to look at some of the key features that describe the parts our Solar System. Quite simply it is the name given to the collection of planets and other bodies that orbit a star. It is only recently by using...

"The Ear

The visible part of the ear is called the pinna. It funnels sound into our e

The sound waves travel down the ear canal toward

The eardrum is a membrane at the end of the ear...
